C# :: Display List Of MSMQ Messages In A List Box
Jan 20, 2015
I'm trying to display a list of MSMQ messages in a list box based on a drop-down list holding the environment.So i've setup the binding and i know that the list loads but nothing shows up in the list? I should be setting like a display member or something but i'm not entirely sure
const String msmqAccelaDev = "FormatName:DIRECT=OS:tcc-intsrvTCCIntegration.MSMQ.Service.Dev/TCCMessagingService.svc";
const String msmqAccelaProd = "FormatName:DIRECT=OS:tcc-intsrvTCCMSMQFail";
const String msmqAccelaTest = "FormatName:DIRECT=OS:tcc-intsrvTCCIntegration.MSMQ.Service.Test/TCCMessagingService.svc";
String currentQueue = "";
private void environmentChange()

vector<int> vec1 {2, 4, 6, 8, 10, 12, 14, 16, 18, 20};
This code worked perfectly fine in Xcode earlier today, but when I got home on visual studio 2012 express it is having an error. It's saying that the local function definitions are illegal and has a red mark under the '{' only?

I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor";
SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon());
SqlDataReader dr = cmd.ExecuteReader();
listView1.Items.Clear();
while (dr.Read()) {
listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString());
}
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.

I want to display data from text file in list view and in tree view root will be file name, but i dont know how to do it, the problem is with displaying text file data in list view, i don't know anything about that. text file data is very simple. It is just a square matrix of double values like:
21.06 34.06 5.0
12.78 45.25 6.9
12.89 45.98 5.5
in list view i want to display it.

I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.

From HP / Microsoft (Visual Studio C++) <list>:
Code:
struct _Node
{ // list node
_Genptr _Next; // successor node, or first element if head
_Genptr _Prev; // predecessor node, or last element if head
_Ty _Myval; // the stored value, unused if head
};
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?

Code:
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
#include <stdio.h
struct entry1 {
int value;
struct entry1 *next;
};
[code]...
This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?

I have a linked list comprised of chars like so...
Code:
node1 - "p"
node2 - "o"
node3 - "p"
I need a function that will take in three perameters...node *replaceChar(node *head, char key, char *str)Stipulations of this function. head is the head of the list, 'key' and 'str' are guaranteed to contain alphanumeric characters only (A-Z, a-z, and 0-9). str can range from 1 to 1023 characters (inclusively). So if I call this function with these perameters..
Code:
node *head == /*the head of the list to be examined*/
char key == "p"char *str == "dog"The new list will look like this...
node1 - 'd'
node2 - 'o'
node3 - 'g'
node4 - 'o'
node5 - 'd'
node6 - 'o'
node7 - 'g'
All instances of 'p' were replaced with 'dog' I have a toString function which takes in a string and converts it to a linked list and returns the head. So assume that you can call the function on str = "dog" so...
Code:
toString(str) == /*this will return the head to the list made from the str*/
If it's unclear what my question is...I am stumped on how to write the replaceChar function the one that takes in three perameters..

Basically i need to encrypt a message into ascii values & i also need to allow the user type some ascii values thus decrypting the values into characters that are placed within the code.
#include <iostream>
#include <iomanip>
#include <cstring>
#include <string>
using namespace std;
#define Q 2000
void main(){
char array1[Q]={"A gentle, dull flickering flame, burns in the marble hearth. Its dim light scarcely illuminates the small, cozy room with its quiet elegance. The dismal light plays softly causing shadows over the solitary figure of a wooden desk at which Allen was roaming through his memories. Thinking back in the past where he once had a friendship which was out righteously incredible. She was the girl of his dreams, in a way which she had everything he had ever sought out in a beautiful and clever girl. Most of all she had his heart. Her style was incredible in the way the outfits she would wear would match perfectly giving a deep vibrant lively feeling."};
int S[Q];
char S1[Q];
int x;
int i;
char e, d;
cin>>x;
if(x=d){
cin>>Q;
for(i=0;i<array1[Q];i++)
cout << S[i]<<endl;
for(i=0;i<array1[Q];i++)
cout << S[i]<<endl;

I'm currently in the middle of designing a program for some project. one part of the program is to send reminding SMS messages to the employees.
I have already subscribed to a SMS provider and they gave me an access to a control panel (aspx). But now I'm wondering how will I be able connect to the SMS server and be able to send messages?

I am new to this area and have the requirement like:
1) A running process wants to send message based on event arrival.
2)the process checks if event is critical
3)if critical then it has to send message immediately ,else send after time t.
4) The process is continuously process the events . so once it knows the event is not critical and has to send message later it has to proceed with its normal operation.. only when time 't" comes it has to come and send message.

Is it possible to alter an error message for a particular line if you think it might fail compilation? GNU specific stuff is okay. The reason I want to do it is because I have this code.
Code:
template <size_t S>
struct assertion{}
int main(){
{
volatile assertion<sizeof(config::input)> asrt = assertion<sizeof(config::output)>();
}
}
If the arrays config::input and config:utput are different sizes, I want it to be clear that that's what needs to be fixed. Is there an __attribute somewhere that will allow me to do that?

I have a property sheet view with few property pages. One of this property page contains a HTML representation via a CHtmlView derived class.
Initially, the .html file is correctly rendered. The problem is that sometimes switching between properties pages sometime the html file is not redraw. The behavior appears randomly.
According to Spy++ in such situation some Windows messages are not sent by WebControl (Internet Explorer_Server layer): WM_ERASEBKGRD, WM_PAINT or WM_NCPAINT.
Approaches such Q179421 or Q183161 are not useful. My machine runs IE 10.
The windows hierarchy is: Shell Embedding -> Shell DocObject View -> Internet Explorer_Server.
Any workaround that would determine Internet Explorer_Server layer to send these messages always?

If it is possible, I'd like to know how to intercept messages sent to controls on a dialog. I'm working on a large application with a large number of dialogs, each with a number of controls on the dialog. I need to be able to intercept messages sent to these controls so that I can determine if the controls really need to take action on these messages. I could subclass each control and override the specific event handlers but due to the volume of controls in the application this could take a very long time, will introduce risk if controls are missed, and will increase maintenance costs. What I want to do is create a class which is derived from CDialog and each of the dialogs in the application would then be derived from this new dialog class. The new dialog class would intercept messages sent to any control on the dialog and if the dialog decides that the control should do something then the dialog will pass the message on to the control.
example:
CExistingDialog is derived from CNewDialog is derived from CDialog
CExistingDialog has a number of controls. When the code in CExistingDialog calls CWnd::EnableWindow on one of these controls I want CNewDialog to intercept the message, determine what should be done with the message, and then pass it on to the control.
I'm not very familiar with the messaging framework. I've tried overriding a few of the methods of CNewDialog but none of them ever receive the message to enable the window. I assume this is because the message is sent directly to the child window (the control).
Is there any way to intercept these messages? I don't know much about hooks either but is this a possible option?

I want to maintain a list. which will update at regular interval. so I thought to with linked list. Earlier I have used linked list.
Code:
typedef struct
{
short nwkaddr;
unsigned char macaddress[8];
}device_t;
}
[code]....
This program is giving many errors. I tried lot to fix it. If I fix one then other bug is arising. for that I did't mentioned what bug i got.Main Issue is while (curr->next->list != NULL) this is giving segmentation fault if i add element second time

#include <iostream>
using std::cout;
using std::cin;
using std::endl;
using std::ios;
#include "Course.h"
#include <list>
[Code] ....
The program works well, except for the fact when it prints out the list (starting at the for-loop on line 65) each line is the same as the last, like it overwrites itself every time it traverses the while(true) loop.

I would like to add a new function to my class, "reverse" that would reverse the order of the list. I have added a prototype in the "public:" section of the code (see the comment with PROTOTYPE in it). Your task is to complete the implementation (see the comment with IMPLEMENTATION in it. See the main() function to see how the results should look
#include
#include
using namespace std;
class List {
public:
// Constructs an empty list
List();
[Code]....
I cant seem to get the right function to put into reverse I have tried everything Im not sure where to start!

I have a concurent queue holding lists, where I have one reading thread and several writing workers. My writers are adding to those lists. Now I just lock the list before I add to it -
if (transaction_calls.TryGetValue(strike, out tranlist)) {
lock (tranlist) {
tranlist.Add(tran);
}
}
Is this enough?
What my reader is about to do, is to see the list size, and reads all the data from list[i] till list[last] - I don't really care for getting the true last, meaning that if while reading list.count, another elment was added, I don't mind ignoring it.
I presume I can't use the foreach on that list, is that right?

Basically, I have a LIST that is saved in a CSV file, and I need to remove a particular record after using the search feature (which populates the fields from the CSV file... i.e. ID, Name, etc...).
I am able to get the details that are in the text fields by using a search feature. This is then put in:
logic.remove(tempIndividual)
In class myLogic.cs, then I have this method:
this.individual.Remove(tempIndividual)
Upon debugging, I can see that tempIndividual is populated with the correct data. However, I need to remove this data from the CSV file. Am I on the right track, or totally off? Maybe it is not complete, cause I can't get to the part where it actually removes the data from the CSV, or at least I'm not sure if .Remove is able to do it on its own.

I work on a system that communicates with other systems via messages. Those messages are defined in a spec and every word must be exactly as defined. To accomplish this Ada allows me to define the fields of my record to specific words in memory.
Code:
word = 4;
type Msg_Type1 is record
x: Some_Type;
y: Another_Type;
z: Another_Type;
end record;

Today I am refining my skills on graph theory and data structures. I decided to do a small project in C++ because it's been a while since I've worked in C++. I want to make an adjacency list for a directed graph. In other words, something which looks like: 0-->1-->3 1-->2 2-->4 3--> 4-->This would be a directed graph with V0 (vertex 0) having an edge to V1 and V3, V1 having an edge to V2, and V2 having an edge to V4, like this:
V0----->V1---->V2---->V4
|
|
v
V3
I know that in order to do this, I will need to create an adjacency list in C++. An adjacency list is basically an array of linked lists. Okay, let's see some pseudo C++ code:
Code:
#include <stdio>
#include <iostream>
using namespace std;
struct graph{
[Code] ....
This pseudocode is currently far from the mark. And that is what -- pointers and structs in C++ have never been my strong suit. First of all, this takes care of the vertices that a vertex points to -- but what about the vertex itself? How can I keep track of that vertex? When I loop over the array, it will do me no good to only know what vertices are being pointed to, rather than also knowing what points to them. The first element in each list should probably be that vertex, and then the elements after that are the vertices it points to.
But then, how can I access this first element of the list in my main program?. I would like to be able to loop over this adjacency list to do some cool things with graphs. For example, to implement some graph theory algorithms (sorts, shortest paths, etc) using the adjacency list representation. (Also, I had a question about the adjacency list. What is different than just using a list of arrays? Why can't I just have a list with an array at each element in the list?)
